Nasal congestion, also know as a stuffy nose, occurs when the blood vessels lining the nasal passages become swollen and inflamed. This process can be due to many factors like allergens, viruses, infections, medications, certain body positions (being upside down) or even increased blood supply like in pregnancy.
Symptoms of congestion are basically the inability to breath through the nose and may be accompanied by a feeling of pressure in the face. This occurs when the swollen blood vessels in the nose tend to narrow the space where air is inhaled. With a narrowed space and increased suction while trying to inhale, a negative pressure system is created that causes the nasal flaps to collapse and further obstruct breathing. Also, the blood vessels that line the passages that connect the sinuses to the nasal cavity can become inflamed and block the sinuses from draining into the nasal cavity. This caused fluid to accumulate in the sinuses, causing the facial pressure, and sometimes leading to a sinus infection.
The treatment of congestion is primarily aimed at decreasing the swelling of blood vessels in the nasal mucosa in order to provide more space for airflow. Decongestants such as Pseudoephedrine (Sudafed), Phenylephrine, Afrin, and Nasal Saline solution are some of the common over the counter remedies used. They act by constricting blood vessels.
Sudafed is an OTC oral decongestant that is very effective in treating nasal and sinus congestion. It comes in regular strength, 12 hour, and 24 hour dosing. One drawback to Sudafed is that it can make it hard for a person to fall asleep. This is were the regular strength or 12 hour dose can be taken in the earlier part of the day so their effect would wear out by the evening. Also, people with high blood pressure should not use pseudoephedrine because it can increase their blood pressure.
Afrin which is a nasal spray decongestant acts locally on the nasal blood vessels to relieve congestion. Its main drawback is that it can only be used for 3 days, because if it’s used longer it can cause rebound congestion.
Nasal Saline is a great natural remedy, especially for someone who doesn’t want to take medications or if certain conditions prohibit them from using decongestant medications. It is safe to use in people with high blood pressure as well as pregnant women because it has a local effect in the nose and not a systemic effect like the other decongestants.
In case of congestion due to an allergic origin, there are combination therapies using an antihistamine to help with the allergic reaction as well. Such products include Claritin-D and Zyrtec-D. One important side effect to bear in mind with antihistamine therapy is drowsiness. The only non-drowsy antihistamine available is Claritin. Concerning effectiveness, Zyrtec-D used to be by prescription only before it recently was released as an OTC. People with glaucoma, asthma, and prostate problems should not use antihistamines because they can make the condition worse.
Finally, you should always check with your physician before taking any OTC medications to make sure that it is safe for you to take them, especially if you are pregnant. Also, many of the OTC medications can interact with other medications that a person may be on, so you could also check with your pharmacist for any possible interactions.
